摘　　要：分析了目前工程模拟器试验时试验点3种配平方法的缺陷,深入研究了飞机配平问题的原理及解算配平问题的优化算法,设计了纵向和横航向多种模式在线自动配平系统,并给出了在线配平系统实现流程。仿真结果表明,工程模拟器实现了纵向和横航向多种模式的在线自动配平功能,并且改进的最速下降法避免了求解解析式,计算量少,收敛速度快,稳定性好,易于工程实现,可以实现全飞行包线内的配平。在模拟器试验应用过程中,在线自动配平系统具备很强的可操作性,提高了模拟器试验效率,能全方位满足飞机型号试验需求,具有重要的工程应用价值。Some deficiencies of three aircraft trim methods were analyzed in engineering simulator test. Basic principle of aircraft trim problem and optimization algorithm for calculating trim problem was in-depth discussion.This paper designed an Multi-mode Online Aircraft Auto-Trim System for longitudinal and lateral-directional trim,and given implementation procedure of the multi-mode Online Aircraft Auto-Trim System. The result shows that the Multi-mode Online Aircraft Auto-Trim System works very well,and modified steepest descent method is con＇ect and effective,which has a low amount of computation, fast rate of convergence,and good stability.It can be easily realized in a project, and can obtain trim state in full flight envelope.The Multi-mode Online Aircraft Auto-Trim System was easy to achieve trimming aircraft, and can meet aircraft type test requirement, and improve test efficiency observably during engineering simulator test. This conclusion is achievable and of important engineering value.
